an improved scatter load for shot gun shells which includes a shotdistributor plug or device, which plug or device is so fashioned orcontoured as to attain the 4desired end in View and which,

ihto the best of applicants knowledge, by the fashioning or contouringof the body of the plug or device, defines surfaces which function toeffect the deection or spreading of different portions of the shot loadin successive stages, yas the load emerges from the vmuzzle of the gunor at some 4point following said. emergence.

4as well to obtain the desired result whether fired from a gun having acylinder-bore or a` full choke-bore.

The invention further provides an-improved means for attaining theresultsr set forth, .which is comparatively simple and not complicatedin its structure, which is inexpensive to produce and incorporate in ashell, which does not materially affect the proportionsof the shell andwhich has proved highly effective in accomplishing the purpose setforth.

With the above recited and other objects in view, reference is had tothefollowing description and accompanying drawing, in which there isexhibited one example or embodiment of the invention, while the claimsdefine the actual scope of the same.

In the drawing:

Figure 1 is an enlarged longitudinal sectiona Ving of applicants device.

Figure 4 is a similar view illustrating a subsequent stagei of*the-'functioning of thedevioe'.

Referring tothe drawing "by characters of reference, 5 designates thebody of a shot gun shell,V 6 the lower or inner wad`s,7 the shotand 8.the top wa-d. The scattering and distributing device or plug, whichdesignated generally by the-referencev character. A, is, inthe formofthe invention illustrated, constructed rof any `suitable material andis preferably secured to -and carried by the top wad 8, so that it maybeemplaced in thel shell with the -top wad.;V As shown, `the device .orplug Afincludes substantially conical leading and trailing portions 9and 1G, which portions Vare each of increasingdiameterfrom the innerendtoward the outer end thereof. The forward end face 11 of the leadingportion 9 abuts with and is preferably adhesively or otherwise securedto the inner face of the top wad 8, while the trailing or rear portion10 is joined at its larger forward or leading end to the leadingorforward portion 9 by a neck l2 which merges into the rear end of theleading portion 9 and the forward enlarged end of the trailing orrear-portion 10, the said neck presenting a substantially conicalsurface which is lof decreasing diameters toward the outer end of theshell when the device is emplaced in the shell, as shown in Figure 1.While in the particular form illustrated the device or plug Aisdisclosed as being provided with only two portions 9 and 10, it is to beclearly understood that more than two of said portions may be employedwithin the scope of the invention. In any event, the trailing or rearportion 10 preferably terminates in a point 13, which point is disposedconcentric tothe axis of the plug and the axis of the shell when thedevice is arranged therein. The configuration or contour of the plug ordevice A as viewed from the side or in prole defines by said neck 12 andthe leading portion 9 a substantially V-shaped peripheral groove G whichextends around the circumference of the plug or device A, and for thepurpose of explaining applicants theory of the functioning of hisinvention, the portion of the shot load, it is thought, which liesbetween the walls of the shell body 5 and the surfaces of the leadingportion 9 and the neck 12, which portion of the shell load is designatedas 7a, is deemed to be influenced by the leading portion of the plug 9as the load initially emerges from the muzzle M of the gun barrel B, asshown in Figure 3, so that this portion of the load is caused to beinitially deecte'd and uniformly distributed over the outer area of theshot pattern.- The remaining portion of the shot f ter of the shotpattern. f

It has also beenrobserved in actual testsrwhich have been conducted thatthe result of the equal distribution of the shot over the area of theshot pattern is substantially the Fsaine Whether the shell is fired froma gun having'aY cylinder-bore or a Iull choke-bore. p p

It should also beunderstood that no limitation is made to the exact sizeor proportionate -size of l the leading and trailing portions 9 and 10,it is felt that changes in the relative sizes andV angularity .of thesurfaces may accomplish results Whichiyvill vary andwhich obviously-`should form apart of this invention. vl 'What is claimed is: s
